T0 LL WHOM IT MAY CONCERN:

Be it known that I, CHARLES FREETSHA, of Paterson, county of Passaic, and State of New'Jersey, have invented a new and improved Pattern Chart; and I do hereby declare that the following' is a full, clear, and exact description thereof, enabling those skilled in the art to fully understand and use the same, reference being had to the accompanying drawing,'in which- Figure 1 represents a plan or face view of this invention.

Figure 2 is a longitudinal vertical section of the same.

Similar letters of reference indicate corresponding parts. l'.llhis invention consists in a chart composed of a series of movable blocks, the different sides of which are colored in di'erent colors in such a manner that', by turning saidblock, patterns of any desired color can be produced, and a weaver, or other operative, is yenabled to represent -a variety of patterns in a short time and with little trouble or expense. l Y

A. represents a frame made of wood or any other suitable material.A The side piee'esof this frame form the 4bearings fora series of wires, a, which support the movable blocks b. These blocks are made4 of wood or any other suitable material, either triangular, square, or polygonal, and their di'erent sides are vpainted or otherwise colored, in different colors. By turning the blooksvontheir supporting-wines, either of their sides can be made to face upwards, and patterns of the greatest variety can be produced without't-ronble. Fior instance, -if the fabric to vbe made istocons'ist of* two colors o nly, or if the warp and weft threads are Vof the same color, and itis desired to produce a pattern'similar to that represented inthe largest part of the frame in fig.

l, the warp threads niay be represented b'ythe black and the weft-threads by the white blocks, and the weaver is ehabledtodeterinine ata glance where .thewarp threads are up and the weft threads are down, or Avice versa.'

For goodsv containing more than'two colors, triangular, cubical, or hexagonal blocks are used, and byvturning .the blocks the pattern is produced. For such patterns which require polygonal blocks, the effect Oof the pattern represented by my blocks islspoiled by the oblique sides adjoiningthose surfaces, which are turned up, and the colors of which arealso visible from above. This defect is obviated by covering said oblique sides with suitl able podisfc', of wood or any other material, which fit in between -the hexagonal blocks as shown in thevdrawing.

It i`s obvious that my pattern' chart may be varied in ahgreat many different ways and used fdr patterns vof textileffabrics or for work of any other description.

What claim as'new, and desire to Ysecure by Letters Patent,.is-

I. A pattern chart composed of a series of movable blocks, the different sides `of which are colored in different colors, substantially a'sand for the purpose herein described.

2. The combination of the covering rods c with the polygonal-pattern blocks, substantially-as and for the purpose herein set forth. y
